I like the time limit. The pool attendant can be the enforcer. Or perhaps, we can use one of the unruly little darlings that nobody brings on board to save the chair until we get back from the bar with our cigarettes. When the unruly little darling that doesn't belong to anybody gets bored and leaves we can offer the fat guy in the speedo another pound of chocolate cake to save the chairs while we sneak cameras onto the topless deck. Then when we are discovered rubbernecking on the topless deck we can cannonball from there into the pool splashing everybody around the pool. When everyone gets up there are plenty of new chairs available. Go for round two!
